// ${generated_comment}

// Generated by tools/jit/gen_unboxing.py. This file declares code generated boxed C++ functions for operators,
// base off of native_functions.yaml (or similar yaml file with the same syntax). The definition of such a boxed
// function will pop out IValues from the stack then convert them into the correct C++ types based on given schema. This
// unboxing logic is an alternative to template-based metaprogramming unboxing.
